INSTALLATION
PRESSURE WASHER
Place machine in a convenient location providing ample support, drainage and room for maintenance (see
page 8).
Location:
The location should protect the machine from damaging environmental conditions, such as wind, rain
and freezing.
1. The machine should be run on a level surface
where it is not readily influenced by outside sources such as strong winds, freezing temperatures,
rain, etc. The machine should be located considering accessibility for the replacing of components
and the refilling of detergents, adjustments and
maintenance. Normal precautions should be taken
by the operator of the machine to prevent excess
moisture from reaching the power unit or electrical
controls.
2. It is recommended that a partition be made between the wash area and the machine to prevent
direct spray from the spray gun from coming
in contact with the machine. Excess moisture
reaching the power unit or electrical controls will
reduce the machine’s life and may cause electrical
shorts.
3. During installation of the machine, beware of
poorly ventilated locations or areas where exhaust
fans may cause an insufficient supply of oxygen.
Sufficient combustion can only be obtained when
there is a sufficient supply of oxygen available for
the amount of fuel being burned. If it is necessary
to install a machine in a poorly ventilated area, outside fresh air may have to be piped to the burner
and a fan installed to bring the air into the area.
4. Do not locate near any combustible material. Keep
all flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor
and walls. (Two feet away should be adequate).
WARNING: Avoid small areas or near exhaust
fans.

tapping accessible for test gauge connection shall
be installed immediately upstream of the gas supply
connection for the purpose of determining the gas
supply pressure to the burner, and to prevent damage to gas valve.
If a manual gas shut off valve is not in the gas supply
line within six feet of the machine and in an accessible
location, one shall be installed.

Venting:
This machine is to be used indoors and requires
ventilation.
When venting the machine, if the machine is to be in
an enclosed area with a vent pipe, be sure it is the
same size as the stack on the machine. Poor draft will
cause the machine to soot and not operate efficiently.
When placing the machine for installation, position the
vent pipe to be as straight as possible and to protrude
through the roof of the building at a proper location and
at sufficient height to eliminate down-draft. Venting of a
gas fired machine shall be installed with a down-draft
diverter located about 3 ft. above machine.

When a room is of unusually tight construction and
has a ventilating fan, which may be used for exhausting air outdoors -or has a vented exhaust — it
is recommended that combustion air be supplied to
the enclosed room through intakes extending to the
outside of the building and terminating in down-turned
fittings. These should be suitably arranged to prevent
obstruction from snow or rain, and include a protecting
screen not smaller than 1/4 inch mesh.

OPERATOR’S MANUAL
Draft Diverter:
Install the draft diverter above the heating coil. The
diverter enhances the draft through the burner by severing the chimney effect created in sections of vent
pipe positioned below. It also helps prevent freezing
of the coil due to wind chill factors.
Figure 3
Optional
When in a tightly closed room without ventilation openings to the outdoors or other rooms, provisions shall be
made for supplying air for combustion through special
openings, one near the floor and the other near the
Illustration showing air openings necessary
to supply air for combustion when installed
in an enclosed room.
Water Source:
The water source for the machine should be supplied
by a 5/8" I.D. garden hose with a city water pressure of
not less than 30 PSI. If the water supply is inadequate,
or if the garden hose is kinked, the machine will run
very rough and the burner will not fire.
Water Connection:
Connect the high pressure hose by pulling the coupler
collar back and then inserting it onto the discharge
nipple. Secure it by pushing the collar forward.
Attach the wand into the spray gun using teflon tape
on the pipe threads to avoid leaks.
Inspection and Testing Gas Piping:
The building structure should not be weakened by
installing the gas piping. The piping should not be
supported by other piping, but should be firmly supported with gas hooks, straps, bands or hangers. Butt
or lap welded pipe should not be run through or in an
air duct or clothes chute.

FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING
If you do not follow these instructions exactly, a fire or
explosion may result, causing property damage, personal
injury or loss of life.
A. This appliance has a pilot which must be lighted by
hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
FOR YOUR SAFETY
"WHAT TO DO IF YOU SMELL GAS"
� Do not try to light any appliance.
� Do not touch any electrical switch, do not use any phone
in your building.
� Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
� If you cannot reach your supplier, call the fire
department.
C. Use only your hand to push in or turn the gas control
knob. Never use tools. If the knob will not push in or turn
by hand, don't try to repair it; call a qualified service
technician. Forced or attempted repair may result in a
fire
or explosion.
D. Do not use this appliance if any part has been under
water. Immediately call a qualified service technician to
inspect the appliance and to replace any part of the
control system and any gas control which has been
under water.
YES NO
Has gas supply been inspected by an
authorized contractor to meet local
codes?
Is machine protected from downdraft and
excessive wind?
Is machine shielded from moisture or
water spray?
Is the voltage correct and are the circuit
breaker and supply cord adequate
according to specifications and serial
plate notation?
Is the machine electrically grounded?
Is there ample water supply?
Have all flammable liquids or gases been
removed from installation location?
Is there adequate gas supply for the BTU
rating of the burner?
Is incoming gas supply pressure between
6 - 14 water column inches or 1/2 PSIG?
Has the proper gas regulator been
installed for pressure and volume?
Is the machine properly vented to allow
adequate air flow?
Are the propane tanks large enough,
according to rating to prevent freezing
(vapor propane machines only)?
Have gas lines been checked for gas
leaks?
Have gas lines been checked with local
codes?
Have all operators using this machine
been instructed properly & have they
read the manual?
Has the machine been installed
according to operator's manual
instructions?
Before turning gas under pressure into piping, all openings from which gas can escape should be closed.
Immediately after turning on gas, the system should
be checked for leaks. This can be done by watching the
1/2 cubic foot test dial for 5 minutes for any movement
or by soaping each pipe connection and watching for
bubbles. If a leak is found, make the necessary repairs
and repeat the above test.
Defective pipes or fittings should be replaced and not

repaired. Never use a flame or fire in any form to locate
gas leaks — use a soap solution.
After the piping and meter have been checked completely, purge the system of air. DO NOT bleed the air
inside an enclosed room.
During pressure testing of the system at test pressures in excess of 1/2 PSIG, the appliance and its
individual shut-off valve must be disconnected from

the gas supply piping system or damage to the gas
valve will occur.

Gas Pressure:
The ideal incoming gas pressure is 11 water column
inches or w.c.i. (min. 6 wc”, max. 14 wc” or 1/2 PSIG).
The correct operating manifold pressure for natural gas
is 3.5 wc” The operating manifold pressure for propane
gas is 10 wc” By adjusting the gas valve pressure
regulator between 3 and 4 wc” a side range can be
achieved for natural gas. Propane is 6-10 wc”.
If the desired input rating cannot be obtained within the
above manifold pressure adjusting range, then the next
size larger or smaller burner orifice should be used.
